' This invention relates to transport wagons, esi

pecially vfor railways, ofthe type which are pro-V vided with a movable lroof `constituted byftwo' swingableV halves, `connected 'to the one endwall I'or both end-walls oi the wagon by means'of arm systems. f

0 section on the lineA-B in Fig. 1.

The mechanismsv hitherto used for transmitting motion to the` halves of the'roof operateysatisfactorily so far as' regards short wagons, but

experience has proved thatin' a wagon of in? ycreased length the spanof the roof will be so great, Vthat there enters a possibility'oi the root becoming warped or being subjected to jamming action.

Besides, the horizontal porsitionof the motion' Y of links 6 are pivotally connected to' the'half of the' roof. The said screw-spindles are journaled transmitting shafts'at theV top -edges ofl 'the side walls ofthe wagon renders possible such an 1njury of the "mechanism, that certain diiiculties,`

may arise in their operation.

According to the invention the transport wagon isprovided with a movable roof, consisting of vtwo swingable halves, and with mechanisms for shifting the same, which mechanisms vare adapted to act upon the halvesofthe roofat points lo.- cated between the ends of the wagon, so that ther halves are well balancedduring opening and closing movements and.Y warping andjamming'are obviated to the greatest possible degree.

The parts of the said nechanismswhich are located nearest to the halves of the roof preferably consist of substantially vertical screw-spinsdles with nuts which are connected to the halves -o the roof in a suitable manner.

worm gears, so that the halves of the roof may be swung into the open and the closed positionsk by means of the said horizontal shafts. v Preferably, the halves of the roof are supported intermediate their ends by swingable. carriersarranged transversely of the wagon, whichfafter the halves of the roof havebeen swung. into open position, may be'swung outwards to the sides of the wagon and do not linterfere:with the loading u and unloading of comparatively long articles.

special motion transmitting The said screw. spindles with nuts are. connected with horizon-. tal shafts by means of gearings, for instanceV undergoes during travel.

(el. 10s-1377) f' 'with a roof constructedin accordance with the According to Figs. 1 and 2 the two halves 1 of the roof are in known. manner swingably mounted by means of arms 2 on trunnions B iixed tothe end walls of the'wagon. For the swinging of the halves of the roof linto closed and open position used, Vas already stated, which mechanisms are connectedtn the halvesio thereof atpoints located between the ends of the wagon. 4'Each of the said'mechanisms comprises a verticalscrew spindles: provided with a nut '5, which lby means xed to the lower ends of the spindles and are engaged by worms 8 provided on a horizontal shaft 9 jcurnaled in the frame of the wagon. Shafts f 9 are provided with cranks l0 through the rotation of which thehalves of the roof are opened and mechanisms are closed. The open position of the halves of the '80 `roof is shown by dotted lines in Figs. 2 and 3.

The 'screw-spindlesfl, nuts 5 and link 6 constitute simple and reliable means for transmitting f the motion to and operating thehalves of the between the ends ofthe latter disadvanageous warping and jamming actions are obviated. kBy

- journaling the shafts 9 in the substantially rigid frame. of the wagon or in the vicinity of the same they are not subjected to warping or bending motions which the body of the wagon'ordinarily Besides, the journaling of theV shafts 9 in the frame of the wagon in- 'volvesfthe advantage that their weight is located i gard to their length. For that reason suitable kcarriers.areprovided transversely of the wagon.

According to Figs'. 5 and-6 the said carriers consist of curved members 11 and 12 which are so constructed that they may be moved aside, so that they do' not interfere with the loading or unloading of comparatively long4 articles. For that purpose the curvedrmembersmay beswingable either as a whole or the members may be constituted by two separately swingable parts. Thus, the left part of Fig. 5 shows the curved member 1l swingable on a hinge 13, so that it may be swung to a position close to. the side of the wagon. The right part of Fig. 5 shows the curved member 12 divided into two parts a and b, which are each swingable on hinges 14 and 15. The construction last mentioned is shown in Fig. 6.

If the invention is applied to an ordinary transport vehicle for instance an automobile, see Fig. 7, itis often suitable that the rear end wall be constituted by two doors. In thiscase it is not necessary to provide any arm 2 at the rear end Wall. Owing to the fact that such carts generally are not so long as railway cars, suicient guiding of the halves of the roof is procured by the arms Y at the top part of side walls, which support the'V rear endsv of the halves 1 of the roof. The nuts 5 provided on .the screw-spindles 4 may be connected directly to the halves of the roof for which purpose brackets 17 extending from the halves of the roof are connected to the nuts by trunnions 18. Consequently, the links 6 are dispensed with in this case. Instead of worm and worm-wheels 7 and 8 toothed gear wheels 19 and 20 may be used. n v

Many other modications of the construction may, evidently, be made without exceeding the limits of the invention.
